SPECIFICATION forming part of Letters Patent No. 478,152, dated July 5, 1892.

To aZZ whom it may concern:

Be it known that I, HENRY O. BRIDGER, a subject of the Queen of Great Britain, and now residing at Wood Ridge, in the county of Bergen and State of New Jersey, one of the United States of America, have invented a certain new and useful Improvement in Devices for Reproducing Characters, Writing, 850., of which the following is a specification.

This invention relates to devices for reproducing messages, drawings, and the like at a distant point; and it consists of the construc tion and novel combination of parts, as hereinafter set forth. r

In the accompanying drawings, Figure l is aside elevation of a device embodying myimprovement. Fig. 2 is a plan view thereof. Fig. 3 is a detail.

Referring by letter to the drawings, A designates a table or platform having a compound movementthat is, the table or platform has a to-and-fro movement and a'lateral movement imparted to it. The table or platform A is mounted and is moved laterally upon a carriage A, which is movable on Ways a, supported on posts 0., extending upward from a bed-plate A As a means to impart a to-and-fro movement of the table or platform A, I employ an electromotor A which may receive its current from any desired source. The electromotor A has a gear-wheel'B on its shaft meshing with a gear-wheel B, having its shaft B mounted on standards erected upon the bedplate A A pitman B extends from the wheel B and is engaged with the carriage A. Obviously by this construction the carriage Awill be moved back a'ndforth on the ways a and carrythe table'A. The end of the shaft B opposite to the wheel BCmay have a balance-wheel B on it, connected by a pitman B with the carriage A to maintain a uniform speed. The electromotor is provided with a governor B It is to be understood that I do not confine myself to an electromotor, as a steam or any other motive power may be em ployed.

A lateral movement is given to the table A by means of a screw 0, rotating in bearings carried by the carriage A and engaging in tapped holes in the framing of the table A.-

On the outer end of the screw 0 is mounted an escapement or similar wheel 0, with which an escapement-lever C engages alternatelyon opposite sides to rotate the screw one step at a time. The lever O is fulcrumed to a bracket extending downward from the carriage A and has a pin 0 extending from its lower portion into the path of tappets o, erected upon the bed-plate. As the table is moved to and fro the lever 0 by coming in contact with the tappets 0, will operate to rotate the screw to impart a lateral movement to the table. To hold one of the ends of the lever C in contact with the wheel 0 until the lever is operated by contacting with the 0pposite tappet, I employ a brake, here shown as a friction-wheel 0 with which the lower 2 endof the leverengages. This Wheel 0 is supported by a spring-arm 0 extending from a depending portion of the carriage A. A

D is a supporting-arm for receiving penD and a transmitting-point or circuit-closer D The arm D is longitudinally adjustable over the table A on the bar D which is secured to posts extending upward from the bed-plate A The posts are preferablyinsulated from the bed-plate by insulating material b As a means for adjusting the arm 'D on the bar D and securing it rigidly as adjusted I have shown the bar D as longitudinally slotted, and a set-screw is extended through the slot into a tapped hole in the arm.

In Fig. 1 I show an instrument D supposedto be at a distant point or station and acting as a receiving-instrument. It is to be understood that the instruments are alike in construction, and each may serve as a trans mitter or aroceiver by changing the electrical circuit, as hereinafter described, and bringing the pen or the transmitting-point into play.

The receiving-pen D is tubular, so that ink may be placed therein and find an exit through a small perforation in the point.

Thepin D is movable or reciprocates vertically in a socket in the end of the arm D and is pivotally secured to an armature E, which coacts with an electro-magnet E, mounted on the arm D.

The armature E is fulcrumed to a post d, extending from the arm D, and a springesecured at one end to the armature and at the other end to the arm D, serves to return the armature and pen to an upward position when the electro-magnet is de-energized.

The transmitting-point of circuit-closer D consists of any suitable metal and is movable verticallyin a socket in the end of the arm 1) adjacent to the pen D. The instrument D preferably has a hard sharp point and the socket is provided with a bushing d of insulating material. The circuit-closer D may be held in yielding contact with paper 011 the table A by means of a spring (1 surrounding the circuit-closer between a pin or shoulder thereon and the lower portion of the arm D, as shown. When the instrument D is not in use, it may be held out of contact with the paper by means of a thumb-screw d engaging in a tapped hole in the wall of the socket and impinging against the instrument.

I will now describe the electrical connections. F F designate batteries, each having a ground-wire G. From the battery F a wire f extends to the electro-magnet E, and a wire f also extends from the battery F to the transmitting-point or circuit-closer D A wire f extends from the electro-magnet E to a switch-point f A wire f extends from the metal table A to a switch-point g, and g is a line-wire extending to the distant re ceiver, and, as shown, the circuit is closed between the wires f" g by the switch 9 Referring to Fig. 2, a message will be seen in place upon the table A. This message is written on paper with metallic ink, and the letters and words of each line are connected to a side line which contacts with the table A or with the wire f.

In operation the transmitting-point or circuit-closer will be placed in contact with the paper, and as the table is reciprocated the point will contact with the metallic ink and close the electrical circuit to operate the receiving-pen on the device D, the current being from the battery F to point D thence through the message and table to wire f, r

through switch g line-wire g, switch g wire 9 electro-magnet F wire g, battery F, and back to battery F through the ground. Of course by changing the switches g g the operations of the machines may be reversed.

Having described my invention, what I claim is- 1. The combination of an electric circuit, a movable table upon which a message is supported, a message of metallic ink on aninsulating material, and a transmitting-point coacting with the message to close the circuit, the said table having a continuous to-and-fro motion and a step-bystep lateral motion, substantially as specified.

2. The combination, with the table having a to-and-fro and a lateral movement and independent mechanism, substantially such as described, for causing each of said movements, of a pen-supporting arm adjustably mounted over said table, substantially as specified.

3. The combination, with an electric circuit, of a pen and table having a to-and-fro and a lateral movement beneath the pen and independent mechanism, substantially such as described, for causing each of said movements, substantially as specified.

4E. The combination, with the pen, of a table, a motor for imparting a to-and-fro movement to said table, and a screw forimpartinga lateral movement to said table, substantially as specified.

5. In a device of the character designated, the combination of the pen, the table, a carriage upon which the table is movable laterally, a way upon which the carriage is movable to carry the table to and fro, a motor for causing such movement, and a screw operated at the ends of the to-and-fro motion to impart a lateral movement to the table, substantially as specified.
